Hi @Davo312 and welcome to the Z-Community.
What you describe sounds like possibly a buffering issue with YouTube?
It's hard say without more specific information, like specifically what apps you are using when this happens.
It's possible your network may be slow, or it is also possible there is something wrong with your device.
If you acquired your device from a carrier, you may want to try taking it into the place where you got it
(Boost Mobile?, Best Buy?) and see if they can reproduce the issue to determine if the device needs repaired/replaced.

Thanks I'm using spotify and xfinity mobile app and it pauses on each one

Have you tried going into the storage settings and clearing the app cache?
You can also try booting the device to the recovery menu, and deleting the cache partition there as well.
Let us know if it helps.
